Package Exports
- @stdlib/math-base-special-gamma-delta-ratio
- @stdlib/math-base-special-gamma-delta-ratio/lib/index.js
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@stdlib/math-base-special-gamma-delta-ratio) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
Gamma Delta Ratio
Compute the ratio of two gamma functions.
Installation
npm install @stdlib/math-base-special-gamma-delta-ratioUsage
var gammaDeltaRatio = require( '@stdlib/math-base-special-gamma-delta-ratio' );gammaDeltaRatio( z, delta )
Computes the ratio of two gamma functions. Specifically, the function evaluates Γ( z ) / Γ( z + delta ).
var y = gammaDeltaRatio( 2.0, 3.0 );
// returns ~0.042
y = gammaDeltaRatio( 4.0, 0.5 );
// returns ~0.516
y = gammaDeltaRatio( 100.0, 0.0 );
// returns 1.0Examples
var randu = require( '@stdlib/random-base-randu' );
var gammaDeltaRatio = require( '@stdlib/math-base-special-gamma-delta-ratio' );
var delta;
var z;
var i;
for ( i = 0; i < 100; i++ ) {
z = randu()*10.0;
delta = randu()*10.0;
console.log( 'gamma( %d ) / gamma( %d + %d ) = %d', z, z, delta, gammaDeltaRatio( z, delta ) );
